The DDS 5900 Digital Discussion System is a conferencing solution with plug-and-play setup and online discussion management. With excellent audio quality and programmable touch-button controls, compact microphone units facilitate clear communication in large groups and meeting spaces. The system manages up to eight talkers at a time and dedicates two channels for interpretation, supporting bilingual events without additional equipment.

The DDS 5900 Digital Discussion System is comprised of one central unit, the control browser, and discussion units for up to 250 participants. Supporting multiple user types, a gooseneck microphone, loudspeaker, and control buttons are combined in a compact discussion unit. With highly flexible layout options and a choice of tabletop or flushmount units, the system seamlessly integrates into a wide range of professional environments, such as:

  • Corporate meeting rooms
  • City councils and regional government bodies
  • Educational institutions
  • Courtrooms
  • Videoconferencing rooms

Features

Clear, Natural Communication

DDS 5900 discussion units enhance group communication, allowing natural conversation to be heard in large meeting spaces. Gooseneck microphones provide excellent speech isolation, while the LED light ring indicates who is talking. A 24-bit digital audio signal is transported to each discussion unit for real-time monitoring from the loudspeaker. Several microphone operation modes provide manual and automatic microphone activations.

Sleek, Professional Design

Modern, low-profile design integrates into a variety of spaces, from historic buildings to contemporary boardrooms. DDS 5900 discussion units are intuitive and functional, reducing clutter and increasing tabletop workspace. Two model variations are available to support the needs of any event:
  • Compact flushmount unit for permanent installation
  • Portable unit for quick setup and easy removal

Flexible Setup and Easy Installation

The DDS 5900 system uses a proprietary protocol to transport digital audio, control data, and power over the same cable (shielded Cat5e). The system supports large events of up to 250 participants, easily scaling with additional components added inline for a simplified layout topology.

Remote Management

For comprehensive system management, open the browser-based control app using a computer or tablet. The interface adds system configuration and discussion setup capabilities, enabling an administrator to prepare the discussion with participant names and seat numbers. The chairman or moderator uses a dedicated page for speaker management during the discussion.

The system is also compatible with Crestron, AMX, and other control systems. The CCU easily interconnects with teleconferencing equipment and external audio components.

System Concepts

The DDS 5900 Discussion system is an important communication tool for meetings of any size. Participants use the discussion unit microphone and loudspeaker to communicate using natural speech levels.

The Discussion Unit: A Personal Sound System

The DDS 5900 Discussion System improves communication amongst a group of people by combining the microphone, loudspeaker, interpretation audio, and user controls in an integrated unit. When a participant speaks, their voice is heard at the other units' loudspeakers. The DDS 5900 is a perfect solution when every participant is both a talker and a listener.

In contrast, traditional sound systems support the communication of one or two speakers to a crowd of people. In those systems, it is impossible to have the dialog required in a discussion setting.

Discussion Participants and Roles

The DDS 5900 discussion unit is programmable to support different functions required by different people involved in the discussion. For example, as the moderator of the discussion, the chairman has an extra control that immediately turns off all delegate microphones. In a typical event, there are three categories of participants:

The following is an overview of each participant role and how they function in a typical discussion.

Delegate (member, participant)

The majority of participants fall into this category. The delegate role is for anyone involved in the discussion that is not a chairman or interpreter. Delegates use the discussion unit to speak and listen to other participants. Depending on the discussion settings, the delegate may send a request to speak before the microphone is activated by the Chair.
  • Up to 250 participants are supported in the DDS 5900 system.

Chairman (chair, moderator, president)

The chairman, or simply the Chair, is the moderator of the discussion. Typically seated at the head of the meeting space, the Chair has the ultimate authority over who is speaking. Using the browser interface, the moderator has ability to turn microphones on or off for specific participants, and view the order in which participants request to speak. Providing immediate control of the discussion, an 'all-delegates off' button is available on discussion units programmed to chairman mode.
  • There is typically only one chairman for each event, though more can be added.

Interpreter

When an additional language is spoken in a discussion, an interpreter provides simultaneous interpretation using the discussion unit. Interpreters select from one of two channels to transmit to other participants speaking the same language. This system supports bilingual, two-way discussion, facilitating the back-and-forth communication between delegates speaking two different languages.
  • The system supports simultaneous interpretation for two languages

Component Overview

The DDS 5900 Discussion System consists of the following components:

① DIS-CCU Central Control Unit

The central control unit (CCU) is the processor for the DDS 5900 system. It provides power and control to the discussion units, analog audio inputs and outputs for external equipment, and a web server that hosts the browser interface for remote system control. Each system uses a single CCU.

② Discussion Units

Participants use the discussion units (DU) to speak and listen to other members of the event. A microphone, loudspeaker, and channel selector are provided for each unit.

Hardware Installation

Microphone units operate by connecting in series from the central unit. Power, audio, and data are transported over a shielded Cat 5e cable from one unit to the next. This topology enables flexible and inexpensive installation for large groups of people.

Rackmounting the CCU

Install the central control unit in a standard 19” rack using the supplied 19” brackets. Remove the screws holding the top and bottom covers, then attach the brackets to the front of the unit using the same screws.

Important: Use the two 10 mm length self-threading screws closest to the front and the 8 mm length threaded screw furthest from the front.

The built-in fan draws air in on the left side and exhausts air on the right, and so does not require extra space above or below for cooling.

Connecting the DCS-LAN Equipment

Shure offers cables designed specifically for the DIS line of conferencing and discussion equipment. The Shure EC 6001 are high-quality Ethernet cables available various lengths from 0.5 m to 100 m. Each cable has been tested to ensure reliable system performance. See the accessories section for ordering information on the EC 6001-xx.

Important: Cables and connectors must be shielded for stable system performance. If an installation does not use Shure EC 6001 cables, they must follow the Cat5e cable requirements.

DDS 5900 Cable Requirements

Cat5e Cable Requirements

Type Cat5e (or higher) twisted pair
Shielding F/UTP or U/FTP
Connector Shielded RJ45
Weight AWG 24
Maximum Cable Length
  • DIS-CCU only: 120 m
  • DIS-CCU with repeater units: 480 m

Important: Cables and connectors must be shielded for stable system performance. If an installation does not use Shure EC 6001 cables, they must follow the Cat5e cable requirements.

Using Patch Panels

When designing a system with a patch panel, crimp the cable to the female shielded connector on the panel. Then simply use short jumper cables to connect to the microphone units. Make sure the chain is always terminated by a microphone unit or a termination plug included in the SPS CU spare parts package.

Connecting Microphone Units and DCS-LAN Components

Microphone units and DCS-LAN components are connected in sequence (daisy-chain) using the two RJ45 ports on each unit. The connectors are interchangeable; simply connect the previous unit to one port, and the following unit to the other port. Always use shielded Cat5e (or higher) cabling for reliable system performance.

Power, control data, and audio are transported from one unit to the next over the same shielded Cat5e cable.

To protect the equipment, ensure that the central control unit (CCU) is always off when connecting or disconnecting the microphone units. Use any of the four chain outputs (A, B, C, and/or D) for connecting DCS-LAN components.

  1. Power off the CCU to protect the equipment during set up.
  2. Connect a chain output on the CCU to the first microphone unit with the shielded Cat5e cable.
  3. Connect the rest of the microphone units in sequence, using the RJ45 jacks on the bottom of each unit.
  4. Turn on the CCU by pressing the power button. The microphone units will power on. The unit is stable once the control button LEDs stop flashing.

    Note: Do not turn off CCU power until the system has stabilized

Connection Diagrams

The following system diagrams illustrate typical hardware connections to the DIS-CCU central control unit. Actual installations may use different combinations of hardware, but follow the general concepts outlined below.

Note: Flushmount and portable discussion units are interchangeable in the following drawings, unless noted.

Basic Setup with Discussion Units

The system is operational without the use of a computer. Use the CCU navigation screen to set up the installation.

Note: This setup does not support the Manual microphone mode, since the browser interface is required for turning microphones on and off.

Basic System with Multiple Chains

Computer for Advanced Management

Connect a computer to the central control unit for comprehensive management of the system through a web browser. Connect an Ethernet cable from the dedicated TCP/IP port to a computer.

Computer Control

Tablet or Laptop for Wireless Control

Use a wireless router to access the web browser from a laptop or tablet. The web browser on a mobile device offers the same comprehensive system management.

Wireless Control

Interpretation Units

The DDS 5900 Discussion System supports bilingual discussion, routing an interpretation channel to each discussion unit. Program the DC 5980 P portable discussion unit for use as an interpretation station. Other participants use the headphone jack on their unit to listen to the interpretation channel of their choice.

Typically, a separate room or booth is dedicated for interpreters for greater sound isolation. Units can connect in any order in the DCS-LAN chain, irrespective of operation mode of the adjacent unit.

Interpretation Units

Audio Recorder

Connect an audio recorder to the analog outputs of the CCU to record floor audio, translations, or a specific set of microphones. Use the browser interface to buss units to groups and assign them to the specific output (A-H). Connect the XLR outputs of the CCU to the inputs of an audio recorder.

Recording Audio

Mixer or DSP

Connect a mixer to the CCU analog outputs to control individual microphone volume or equalization. Use the browser interface to buss units to groups and assign them to the specific output (A-H).

To return the audio to the DDS 5900 system:

  1. Connect the output of the external device to Audio Input 1 on the CCU
  2. Route the Input 1 audio by selecting the Loudspeaker and Ch. 0 and deselecting Out A (Group) Audio > Input Control > Audio In 1
  3. To avoid a feedback loop, turn off the internal Floor routing by deselecting Loudspeaker and Ch. 0: Audio >  Input Control > Floor

Inserting a Mixer or DSP

Wireless Language Distribution

For additional monitoring, connect a wireless language distribution system to one of the CCU audio outputs. Use the browser interface to select the desired microphones (seat) for that group output (A-H). The DCS 6000 Digital Infrared Language System transmits this audio signal to a number of listening stations.

Wireless Language Distribution

Emergency Signal

Input 2 is designed to broadcast an Emergency Evacuation Message (EEM), overriding the discussion in the event of an emergency. A switch (normally-open) must be connected to the emergency switch connector. When the switch is closed an "Emergency Evacuation Message (EEM)" audio signal present on the 'In 2' input is distributed to all output channels, overriding all other audio inputs.

Power Requirements

For most installations, the DIS-CCU supplies sufficient power for the discussion units. Depending on the setup, the CCU powers up to 50 units at a time without additional equipment. The number of supported discussion units depends on the size and layout of the installation.

Note: maximum cable length in one chain is 120 m before a repeater unit.

Power Depends on Installation Variables

To maximize the unit count without adding equipment:

  1. Use multiple chain outputs from the CCU. Units must be divided evenly across each chain
  2. Position the CCU so that the cable distance to the discussion unit chain is as short as possible
  3. Keep the total cable length as short as possible by decreasing space between units

Discussion Units Powered by the DIS-CCU

The following tables show how to connect the most discussion units without adding additional equipment.

Note: When using multiple chains, distribute the number of units evenly across the chains to maximize unit count.

1 m Spacing Between Discussion Units

Cable length from CCU to the first unit Estimated Number of Discussion Units Powered from CCU
One Chain Two Chains Three chains Four chains
10 m 43 47 48 48
30 m 39 45 47 48
50 m 36 43 45 46
100 m 21 38 42 44

2 m Spacing Between Discussion Units

30 m 37 44 46 48
50 m 34 42 45 46
100 m 11 22 33 43

Note: Power requirements for the DC 5900 F discussion unit vary depending on the configuration of the unit. Additional discussion units are supported when the loudspeaker is removed and when GM gooseneck microphones are used instead of the MX4xx series microphones.

Using Junction Boxes

The JB 6104 junction box adds four additional outputs to a point on the DCS-LAN chain. These four outputs are available for short-run connections to DUs, protecting the DCS-LAN chain from technical failures or hot-plugging damage. A single DU can connect to each JB output, with a maximum cable length of 10 m.

1 Chain, 2 Units per JB 6104

Cable length from CCU to the first unit Cable Length Between each JB 6104 Number of JB 6104 Maximum Number of DUs
10 m 3 m 19 37

Installing Large Systems

Power Supplies for Additional Components

To add additional components to the system, add an inline or rackmount power supply to the discussion unit chain.

Inline Power Supply

Use the PI-6000 power inserter to add an inline power supply for approximately 50 more discussion units. The unit may be connected at any point in the chain to power the additional components. Multiple PI-6000 units can be used to reach the maximum 250 supported discussion units.

Note: The PI-6000 does not refresh the data signal, so total cable length cannot exceed 120 m.

Inline Power Supply (1x)

Rackmount Power Supply for 4 Additional Chains

Use the EX 6010 rackmount extension unit to add additional components and configuration options. The unit expands the discussion unit chain into 4 separate outputs, each with a power supply equivalent of a CCU (approximately 50 units).

Note: The EX 6010 also refreshes the data signal, enabling an additional 120 m of cable from each port.

Rackmount Power Supply (x4)

Extending Total Cable Length

The CCU operates a system with up to 120 m of shielded Cat5e cable. To add more cable for large or more complex installations, add an RP 6004 Repeater before 120 m limit has been reached.

The RP 6004 connects anywhere in the DCS-LAN chain, refreshing audio and control data for the units that follow it. It provides four additional chain outputs that each operate for an additional 120 m.

The signal can be refreshed up to three times for a maximum cable length of 480 m.

Note: This unit does not add any power for components in the chain.

Installation Best Practices

Follow these guidelines for the most reliable installation.

Continuity of Shielding

Shielding must be consistent through the DCS-LAN chain. Any cable or patch panel used for DIS components requires shielded RJ45 connectors. All DIS components feature shielded RJ45 female connectors.

Avoiding Accidental Grounding (Galvanic Isolation)

Avoid accidentally grounding the DCS-LAN signal with the chassis ground of a patch panel. The DCS-LAN uses the shield as a signal ground reference and cannot contact another ground anywhere in the connection.

Avoid Grounding in a Patch Panel

To avoid ground issues:

  • Plastic frames in patch panel: this ensures that the female JR45 connectors do not ground to the chassis of the patch panel.
  • Blank space between connectors: leave a space between each female RJ45 connector in a patch panel.
  • Shielding continuity: each component in the chain must be shielded properly.

Note: The female connectors in all DIS components units feature an air gap that isolates the chassis of the connector and the chassis of the unit preventing any galvanic (physical and thus electrical) connection.

Properly Securing Cables

As with any cable carrying a signal, use care when installing the equipment.

Bending Rule

Do not sharply bend the cable. Ethernet cables cannot bend more than four-times the diameter of the cable.

Pinching

Do not over-fasten the cable. A pinched cable may not operate correctly.

Using the Discussion Units

Attach the Touch-Button Overlay

Attach the touch-button overlay to each unit for basic microphone control. The discussion units use soft buttons that change functionality when programmed to different unit types. Button overlays are supplied with the discussion unit or with the central unit.

Warning: Overlays are not reusable. If a unit needs to be reconfigured, carefully remove the overlay and apply another one.

  1. Choose an overlay for the unit.
  2. Remove the protective paper from the back.
  3. Place the overlay in the recess on the front of the unit.

Securing the Microphone

To lock the microphone into place, use the supplied hex key and turn counterclockwise.

DIS GM: Simply insert the microphone into the XLR socket. Adjust the gooseneck for proper position.

Shure MX4xxRLP: Attach the AC 5901 XLR/Microflex adapter to the microphone. Insert the adapter into the XLR socket of the flushmount unit.

Program the User Type

DDS 5900 discussion units are programmable, changing the function of the control buttons to support different user types. The three types are chairman, delegate, or interpreter, each requiring unique control functionality. The setting is stored in the unit, and persists after a power cycle.

Note: Flushmount units are not programmable as interpreter stations. Use the portable DC 5980 P unit for simultaneous interpretation.

Flushmount Units

To program the flushmount DC 5900 F discussion unit as a chairman or delegate, simply attach the button overlay. The overlay automatically programs the unit with the correct button functionality.

Reboot the system once all the overlays are attached to establish the configurations with the CU.

Portable Unit

Program the portable units by pressing the volume buttons and scrolling to the desired mode.

  1. Power on the unit by properly connecting it to the DCS-LAN chain.
  2. Press and hold the '-' and '+' volume buttons. The Speak light flashes to indicate the unit is ready for programming.
  3. While continuing to press the volume buttons, press the channel scroll to the unit type. The type is indicated by the combination of channel LEDs; see the table below.

Changing Unit Type

Unit Type Ch. 1 Ch. 2

System Set Up

Web Interface

For comprehensive management and remote control of the system, open the web interface on a computer or tablet. The central control unit (DIS-CCU) provides a web server for system control from a web browser on a networked computer. The web app offers advanced parameters for setting up the system, and enables the chairman or moderator to manage microphones using participant names and seat numbers.

Note: The computer network is separate from the component network (DCS-LAN).

DDS 5900 Web Interface

System Requirements

For best performance, always update the browser to the latest released version. The following browsers function properly with the system interface:

  • Internet Explorer (IE) 8+
  • Firefox 10+
  • Safari
  • Chrome
  • Opera

Open the DIS-CCU System Interface

Follow these instructions to open the browser interface on a computer.

Connect to the CCU

  1. Connect the computer to the TCP/IP port on the CCU.
  2. Power on the equipment.
  3. Assign the computer to automatically obtain an IP address. This enables the computer to automatically connect to the CCU.
  4. Acquire an IP address by selecting Dynamic from the LAN Setup  > Acquire IP addr. window.
  5. View the IP address: LAN Setup  > IP address setup .
  6. Open the internet browser in the computer.
  7. Type 'http://IP-address', where 'IP address' is the address noted from the CCU.
  8. The browser interface opens.

Assigning the Network Address

Access to the system interface is available from two network addresses: IP address and hostname. Typing either address into a browser will access the interface of the connected CU.

Manage the network address from the browser: System > LAN Setup

IP Address

Select 'Dynamic' if the CCU is connected to a network with a DHCP server. Otherwise select 'Static' and assign a fixed IP address to the CU. Default IP configuration is "Dynamic".

Select 'Apply Changes' to save the changes made.

View the IP address from the CCU front panel:

LAN setup >  IP address setup >  IP address > Actual IP address .

Hostname

The hostname is a user-defined name that can be assigned to the device to access the browser instead of using the IP address. The hostname is titled in a logical manner to easily identify the component on the network. More importantly, the hostname will not change on its own (unlike the IP setting), making it ideal for bookmarking.

For example, if the system is set up in the primary meeting room, the hostname could be called, "MainRoom" resulting in the address: http://mainroom.local.

  1. Go to the LAN Setup page.
  2. Under CCU hostname, select the default name and delete it.
  3. Enter the new hostname.
  4. Select the Apply Changes button to save the name.
  5. Check the address by typing into the browser: http://hostname.local
  6. If desired, bookmark the page.

Language Setting

The browser interface is supported in a variety of languages. Go to System > Language to select the desired language.

Additional Interface Pages for Meeting Participants

In addition to the administrator access to the web interface, there are two separate addresses useful to the participants during the meeting:

  • Microphone control for speaker management
  • Display-only page for meeting participants to view the speaker lists

By default, anyone can access these views from a computer or mobile device connected to the network. To protect these pages, the administrator can assign a password to each from the Security page.

Microphone Control Page

This page is dedicated for microphone control during the meeting. Use this view as a chairperson or meeting operator to manage speakers, speak requests, and replies.

For access, enter the IP address of the CCU, followed by /chairman (example: http://172.17.11.137/chairman).

Display Page

The display page is used to provide the meeting participants with a view of the speaker, speak request, and reply lists.

For access, enter the IP address of the CCU, followed by /display (example: http://172.17.11.137/display).

Tip: Put the page in full-screen mode during the meeting:

  • PC: F11
  • Mac: ctrl + cmd + f

Security

DIS components use a proprietary codec algorithm to prevent unauthorized devices from listening to the audio signal. To further protect the discussion, assign a password to the browser interface and enable security features on wireless routers.

Password Protect the Browser Interface

You can assign a password to restrict access to the browser interface. An independent password is assignable to each of the three interface addresses: administrator, chairman, and display.

  1. Sign into the browser interface as an administrator.
  2. Go to the Security page ( System > Security )
  3. Enter a valid user name and password.
  4. Select Change Password to save the login information.

Note: passwords are cleared when the unit is reset to factory default settings.

Removing the Password

To clear the password access to the CCU, restore factory default settings.

Note: Resetting to factory defaults will erase all delegate, system, and IP settings.

From the Hardware

  1. Go to the front panel of the CCU.
  2. Scroll the main menu to Restore Factory Defaults
  3. Press the center button to enter menu
  4. Press the center button again to confirm the reset.
  5. Wait for the system to reboot. The computer will lose connection to the browser interface during this time.

From the Browser Interface

  1. Open the CCU browser interface
  2. Go to Configuration > Factory Defaults
  3. Select the Reset button to reset the system.
  4. Wait for the system to reboot. During the reboot process, the computer cannot access the browser interface.

Isolating the Network

For maximum security, isolate the control network with a dedicated computer or a protected router.

  • Dedicate one computer as the control station. Connect it directly to the CCU TCP/IP port. This ensures that wireless devices cannot access the IP address of the control software.
  • If multiple computers or tablets are required, assign a password encryption for the router. The most effective standard is the Wireless Protected Access II (WPA2), which uses Advanced Encryption Standard (AES) for encryption. Reference the router user guide to set it up.

Assigning Names and Seat Numbers

When the discussion begins, the chairman or discussion moderator will need to refer to the participants by either name, seat number, or both. The proper assignment of names and seat numbers is critical to ensure the continuity of the discussion.

When logging in with the browser interface to an installation for the first time, each microphone unit appears with its default name. Units are automatically assigned a seat number. Chairman units also appear in the participant setup page. Use the participant setup page to match the units to the anticipated seating chart.

  1. Make sure all units are connected and functioning.
    • Go to the System Status page for details System > System Status
    • All properly connected microphone units are listed with a default serial and seat number automatically assigned by the software.
    • Disconnected units will display as Lost and can be removed from the list by selecting Remove Unregistered Units
  2. Reassign seat numbers to match the actual seat numbers in the room or on your seating chart.
    1. Go to the Unit to Seat Relation page Configuration > Unit to Seat Relation .
    2. Match the entries in the seat table to the corresponding units in the room by placing the cursor over the seat number field. The light ring on the microphone flashes red.
    3. Change the seat number by clicking in the field.
  3. Draw a seating chart, or diagram, that represents the room. Number each seat that requires a discussion unit. Add participant names to the seating chart.
  4. Go back to the Participant Setup page Configuration > Participant Setup and change the descriptions next to the assigned seat numbers to the appropriate participant names.

Reassign Seat Numbers

Add Participant names

Audio Settings

The Floor Mix

When a microphone is turned on, the audio is routed to the main mix (Group A) by default. This mix is often referred to as the floor mix because it transmits the audio from anyone participating in the meeting. Interpreters also listen to the floor to provide language interpretation for multilingual discussions.

By default, the floor mix is routed to the loudspeaker and headphone output (Channel 0) of each connected microphone unit.

Route Microphones to Groups

Go to the Group Setup page Audio > Group Setup to view or modify the microphone routing.

For each microphone, select one of the following options:

  • Group A only (default)
  • Group A + another group
  • Group B, C, D, E, F, G, or H
  • None

Floor Mix on the Loudspeakers

Loudspeakers are included in most microphone units for localized sound-reinforcement of the discussion. When a participant uses their microphone, their speech is heard at other unit loudspeakers. This improves speech clarity in large rooms and reduces typical problems associated with sound reinforcement systems.

A Loudspeaker for Each Participant

Each participant can listen to the discussion on a personal loudspeaker attached to the microphone unit.

  • Flushmounted DC 5900 F: The flushmount unit requires the attachment of the LS 5900 F loudspeaker.
  • Portable DC 5980 P: Each portable discussion unit includes an integrated loudspeaker.

Note: To avoid feedback, the loudspeaker is turned off when that microphone is active.

Loudspeaker Adjustment

Loudspeaker volume is a system setting that applies to all connected units. Volume is adjustable from -0 dB (no attenuation) to -40 dB, including off (mute). To adjust the volume:

From the Browser Interface

Go to the Loudspeaker Control page ( Audio > Loudspeaker Control )

From the CU

Scroll to the Loudspeaker Menu ( loudspk. control > loudspk. volume > db )

Headphone Channels

Most microphone units include a headphone output for listening to interpreter channels or other participants on the floor channel. Each participant chooses their channel from the microphone unit channel selectors.

Channels 1 and 2 are dedicated for language interpretation. Participants select one of the channels to listen to their language during a bilingual event. The audio source comes from interpreter stations transmitting onto their selected channel.

Channel 0 (the floor channel) is used by interpreters to provide simultaneous interpretation of the discussion. This channel is also selectable by other participants to listen to the floor channel on headphones (channel 0 = LEDs off).

Use Headphones for Language Interpretation

  1. Connect headphones to the headphone jack on the side of the discussion unit.
  2. Select a channel by pressing the selector buttons on the front of the unit.
    • Channel 0 - Floor Mix (LEDs off)
    • Channel 1
    • Channel 2
  3. Adjust the volume of the headphones using the + or - buttons on the unit.

Audio Source for the Loudspeaker and Headphones

By default all microphones are routed to loudspeaker and headphone mixes.

To change the audio source:

  1. Route microphones to Group A to add them to the floor mix (all selected by default) Audio > Group Setup

  2. Select the audio sources for the loudspeaker and Channel 0 (headphone) Audio > Input Control :
    • Floor (default)
    • Audio In 1
    • Audio In 2

Analog Audio Outputs

Eight analog outputs are available for recording, language distribution system, teleconferencing unit, or an external PA system.

Eight Analog Outputs

Go to Audio > Output Control and choose from the following options:

  • Group: Eight separate groups for isolating specific microphones. This selection corresponds to the groups configured from the Group Setup page.

    Note: If the group buss is not used for the corresponding XLR output, it is unavailable in the routing matrix.

  • Ch. 1 & 2: Interpretation channels
  • Floor: The audio from all open microphones that are routed to Group A (floor mix). There are three variations on this mix to chose from:
    • Ch. 0: Headphone mix with AGC, useful for sending to an IR language distribution system.
    • Floor 1: Loudspeaker mix, useful for sending to a PA or broadcast equipment.
    • Floor 2: Loudspeaker mix with volume attenuation ( Audio > Loudspeaker Control )

Adding an External Audio Source

Two inputs are available on the DIS-CCU for adding an external audio source to the system, often useful for teleconferencing or internet calling.

  1. Connect a line-level audio source, such as the audio output of a computer, teleconferencing unit, or wireless microphone system to the audio input on the DIS-CCU back panel.
  2. Open the web interface to Audio > Input Control .
  3. Select the input gain according to the output of the external device. If necessary, select 10 dB for a slight gain boost.
  4. Select the routing for the audio channel:
    • Loudspeaker: to all microphone unit loudspeakers
    • Ch. 0: to the headphone output on the microphone unit
  5. If desired, route the channel to Output A (Group) to output a blend of the external source with the microphone units:
    • Deselect for teleconferencing or signal processing to avoid a feedback loop
    • Select for a microphone to be blended with other discussion unit audio
  6. Adjust the volume of the audio input to mix naturally with speech levels at the discussion unit.

Input Control Page

Emergency Audio Signal

To prepare for an emergency, connect an Emergency Evacuation Message (EEM) audio signal to Input 2. The block connector provides a 'normally-open' switch that when closed, distributes the emergency signal to the loudspeakers and all input and output connections.

Important: When the switch is used for Input 2, the EEM audio signal bypasses the volume and on/off settings. Control the volume of the EEM signal at the source output.

  1. Connect the EEM signal to Input 2.
  2. Connect a switch to the block connector.
  3. Close the switch and test the audio signal. Adjust the volume at the audio source to the desired level.

Running a Discussion

Microphone Operation Modes

The operation mode determines how participant microphones function during a meeting. Several factors may affect the meeting requirements and the manner in which the meeting is run: room size, number of participants, formality of the event, and amount of technical support on staff. The operation mode addresses these factors with four presets to control the microphone behavior.

To change the mode:

  • CCU hardware: Delegate Setup > Operation Mode
  • Browser interface: Operation > Operation Mode or from the Microphone Control  page.

Description of Operation Modes

The following is a description of each mode once the Speak button is pressed:

Auto (Automatic)

Automatically turns on the participant microphone if there is room in the speaker list. In this mode, there is no request queue: if the Speaker List is full, the participant microphone does not turn on.

Manual

Adds the participant to a request queue that is managed by the chairman. The Chairman selects participant microphones from the queue list, and turns them on and off. Manual is the only mode in which the web browser is required to manage talkers.

FIFO (First In, First Out)

Automatically turns on the participant microphone if there is room in the speaker list. Once the list is full, participants are placed into a chronological request queue. The microphone turns on automatically once a space is open in the speaker list.

VOX (Voice Activation)

The microphone automatically turns on when a participant talks into the microphone or presses the Speak button. The microphone automatically turns off after the talker is finished. In this mode, there is no request queue: if the Speaker List is full, the participant microphone does not turn on.

Speak Interrupt Mode

This mode determines the behavior of the microphone units when the speaker list is full:

  • Off (default): A participant unit cannot turn on until a space is available in the speaker list.
  • On: A participant can turn on the microphone even when the speaker list is full. This turns off the microphone of the participant that has been in the list the longest (at the bottom of the Speaker List).

Speaker List with a Maximum of 3 Speakers

When Speak Interrupt is on, a participant that turns on their microphone will override the last person in the speaker list.

Controlling the Discussion Unit

DDS 5900 discussion units are programmable during setup to support the role of each member of a meeting.

Chairman

As the leader of the event, the chairman has several unique features enabled on the discussion unit.

  • All-Delegate Off: For meeting management, the chairman uses this button to instantly turn off all delegate microphones and clear the Speaker list.
  • Speak:The chairman can always turn on the microphone, overriding delegate units even when the maximum number of open channels has been exceeded. Therefore, there is no mute button; the chairman simply presses the Speak button to turn the microphone on and off.

Delegate

Delegate units contribute to the main audio mix called the floor mix. The number of simultaneous delegate speakers is limited, requiring different control buttons to participate in the discussion:

  • Speak: Turns on the microphone or adds the user to the request queue, depending on the system settings. Microphone status displayed by the button LED:

    Red = microphone is on

    Green = microphone is in the request queue

  • Mute: Temporarily mutes the audio from the microphone. While the button is pressed, the delegate retains speaking privileges but the microphone will not pass audio to the floor sound.

Interpreter

The primary function of the interpreter unit is to translate the discussion into a foreign language. Participants that do not speak the native language of the discussion rely on the interpreter to participate. Interpretors listen to the floor sound

  • Interpretation Channel Send: The interpreter selects one of the two channels for transmitting language interpretation.

Interpretation stations can only be assigned to the Portable 5980 P discussion unit.

Speak Button Settings

Make additional adjustments to the unit speak button from Operation > Operation Mode .

Preventing Accidental Microphone Deactivation

Speak Button Lock prevents conflicts that can occur when two people attempt to perform the same action on a unit. The lock temporarily disables the speak button, preventing a participant from overriding an action set by the operator and accidentally turning off their own microphone. Assign a lock duration between 1 - 120 seconds.

Tip: To override the lock, press and hold the speak button for the duration assigned to the Lock Override Time (1 – 120 seconds).

Disabling Microphone Off From the Unit

Allow or prevent participants from turning off their microphones using the speak button on the unit:

  • Allowed: The participant can turn off the microphone using the speak button on the unit (default setting).
  • Not Allowed: The microphones can only be turned off by the chairman or operator.

Maximum Speaker Setting

To improve speaker management and clarity of the audio, there is a limit to the number of speakers at the same time. Up to eight chairman and delegate microphones can be open at once. There are several settings:

Note: Interpreter units are always active and do not impact the speaker list.

Max speakers

  • Total: Total number of open participant and chairman units. This is the absolute maximum number of people that can address the floor at once.
  • Delegate: Number of delegate microphones that can be open at one time (excludes the chairman).

Maximum Requests

Total number of participants that can be in the request queue at one time.

Example Settings

Chairman (Moderator) Can Speak At Any Time

Set the total number of speakers to one (1) higher than the maximum number of participants. If there are two chairmen, set the number to two (2) higher.

Using FIFO Mode

First In, First Out (FIFO) mode automatically turns on microphones based on a chronological queue list. This mode works best if the maximum number of participants is set to one (1), so that the participant must wait to speak until the other is finished.

Voice Detection

Voice Activation (VOX)

In VOX mode, the microphone activates automatically once a participant speaks. The mode is ideal for meetings that are more conversational, allowing back-and-forth communication that doesn't involve speak requests and button activation. The following settings allow VOX to be customized for the meeting:

Voice Detection Threshold

Determines the input level (dB) that activates the microphone. Lower settings activate the microphone with a quieter source, while higher settings require a louder source to activate the microphone.

Default

0 dB

Minimum

-12 dB

Maximum

8 dB

Release Time

Determines how long a microphone remains active after a participant stops talking. The setting is selectable in 0.5 second increments.

Default

4 seconds

Minimum

1 seconds

Maximum

10 seconds

Book Drop

To ensure that only the speech from a participant activates the microphone, turn on the book drop feature. This quickly turns off a microphone that has been accidentally activated from a loud noise other than speech.

Last Mic Stays Open

This setting ensures that at least one microphone is always activated. This is useful for video or audio conferences with echo-canceling equipment.

Auto Off

This setting automatically turns off the microphone when the participant stops talking.

  • Off (default)
  • On

Automatic Off Time

The time for a microphone to turn off after the participant stops speaking.

Default

20 seconds

Minimum

5 seconds

Maximum

60 seconds

Managing Speakers from the Web Browser

For increased control over the meeting, the chairman uses the browser interface to activate microphones. The chairman page is dedicated for controlling the speaker list and request queue. The chairman can manually turn on/off microphones, or simply monitor the list in an automatic mode. Using the interface, the chairman can easily:

  • Click on a participant name to turn on the microphone, or add them to the request queue.
  • View who is speaking and who is waiting their turn to speak

There are two main lists from the Microphone Control page:

Speaker List (Red)

The speaker list displays the name and seat number of each active microphone. The list displays in chronological order, with the most recently activated microphone at the top of the list. A red box turns on next to the seat number for quick visual identification.

Request Queue (Green)

Delegates in this list are next up for speaking. Primarily useful when operating in First In First Out mode (FIFO), the queue chronologically lists all participants that have pressed their speak button. Once an opening is available in the speak list, the participant at the top of the queue list is automatically turned on.

Open the Chairman Page

For access to the chairman page, enter the IP address of the CCU, followed by /chairman (example: http://172.17.11.137/chairman).

Controlling Participant Microphones

The following buttons are available to the chairman for controlling the microphones during a meeting:

Speak

Instantly turns on a participant’s microphone. Select this button to view all discussion units in the system, including those in the request queue. Select a participant to add them to the Speak list.

Request

Add a participant to the request queue to put them in line for speaking. Select from any participant in the system, excluding the chairman.

Next On

Activates the participant microphone at the top of the request queue. If the maximum speaker count has been reached, the new speaker replaces the last one on the list.

All Del. Off

Turns off all participant units, leaving only the chairman in the speaker list. The same button appears on the chairman discussion unit.

All Req. Off

Removes all participants from the request queue.

Language Interpretation

There are two additional audio channels used for language interpretation. In bilingual meetings, participants speak their native language into the microphone and listen to the interpretation on headphones.

Example Setup for Bilingual Meeting

Interpreters use the portable DC 5980 P to transmit simultaneous language interpretation of the discussion. Participants listen to their desired language channel on any microphone unit with a headphone output.

Set Up Interpretation Channels

  1. Begin by programming the portable DC 5980 P as an interpreter station.
    1. Power on the unit by properly connecting it to the DCS-LAN chain.
    2. Press and hold the '-' and '+' volume buttons. The Speak light flashes to indicate the unit is ready for programming.
    3. While continuing to press the volume buttons, press the channel button. Interpreter mode is set when both channel LEDS are illuminated.
  2. Select one of the two channels for audio transmission from the interpreter unit. The channel LED will illuminate to indicate the selected channel.

    Note: Multiple microphone units can be set for the same interpreter channel to support multiple interpreters at once.

  3. Program another DC 5980 P for the second language and select the other channel for transmission.
  4. For each participant in the meeting, select the headphone channel that corresponds to the interpreter language. Listen to the interpretation channels on any microphone unit with a headphone output.

Note: Flushmount DC 5900 F units are not programmable as interpreter units.

Troubleshooting

Attention: Always use shielded Cat 5e (or higher) network cables for reliable system operation. Ensure the right cables are used and installed correctly before referencing the troubleshooting table.

The light rings on the microphone are constantly flashing after the system is powered on.
  • Check that cables are shielded Cat 5e (or higher)
  • Ensure that all the connectors on all the cables are firmly inserted in the sockets on the units
  • Check that the feed cables from the microphone units are properly inserted into the 'DCS-LAN' socket on the DIS-CCU.

External Control Protocol

The DIS-CCU features an Ethernet connection for the purpose of providing an interface to control and monitor the system. By setting up a simple (raw) TCP/IP socket connection to the DIS-CCU Central Unit, control options are available.

This section describes the TCP/IP raw socket protocol for communicating with the DDS 5900 Discussion System. This protocol provides a short set of commands, enabling a third-party control application to monitor and/or control system status of a DDS 5900 Discussion System.

Some examples of functionality available using the protocol:

  • Setting a microphone in speak or in request
  • Retrieving a list of seats available in the system.

This interface supports applications developed by customers, so the protocol is deliberately kept simple. The External Control protocol offers a means for supplementing the control functionality available through the DDS 5900 Browser interface and the DIS-CCU interactive display, however some commands and settings available in the browser interface and on the DIS-CCU interactive display are not available using the 'External Control Protocol'

Customer applications can include but are not limited to AMX® or Crestron® room control systems, PC or micro controller based applications, e.g., for button mimics and camera control applications.

General Protocol Behavior

TCP/IP socket connection

A TCP/IP socket connection to the DIS-CCU must be established for the External Control protocol to become available. Configuration of the DIS-CCU connection to the Ethernet must be defined from the CCU interactive front plate control/Browser interface and an IP address for the DIS-CCU must be assigned in the network.

Choose either a static IP address or an IP address assigned through DHCP. It is convenient to ensure, that the DIS-CCU ends up with the same IP address at each start up.

Knowing the IP address, the only additional information required for setting up a TCP/IP connection is the Port Number:

Port Number = 3142

Example: Test connection to CCU via Putty®: If the DIS-CCU is assigned IP address 192.168.1.100, the external application must connect the TCP/IP socket to the address 192.168.1.100:3142.

Knowing the IP address of the DIS-CCU a connection can be set up using a simple terminal program like Putty.

  1. Download at www.putty.org
  2. Start Putty.
  3. Insert IP address and Port Number.
  4. Select 'Raw' for the Connection Type.
  5. Press 'Open' to establish connection to the CU. Control is now possible.
  6. Type 'help' to see a list of commands available.

Command Structure (from External Control to DIS-CCU)

To control the CCU an External Control sends commands to DIS-CCU included in command lines. Command lines are build up in a very simple manner:

<command><SP><data><CR>
<command><SP><data><LF>

<SP> Space - 0x20 = 32
<CR> Carriage return - 0x0D = 13
<LF> Line Feed - 0x0A = 10

Command lines are terminated by a Carriage Return <CR> or Line Feed <LF> or both. In order to be able to communicate with Windows systems, Linux systems or other systems, the CCU understands both types of command line terminations.

Notice also, there is a space between the command and data. If a command does not carry any data, space is possible but not required.

The CCU is not sensitive to upper/lower case.

Example:

mic_on 212<CR>

Turn on microphone at seat 212. Command = mic_on, data = 212. The 'mic_on' command carries a seat number as data.

Command Structure (from DIS-CCU to External Control)

Command lines out of the DIS-CCU are just as simple:

<command><SP><data><CR><LF>

<SP> Space - 0x20 = 32
<CR> Carriage return - 0x0D = 13
<LF> Line Feed - 0x0A = 10

Again, to satisfy most systems, the CCU terminates command lines by including both <CR> and <LF>.

Seat Numbering

Discussion Units are identified by means of a seat numbers. Each Discussion Unit is assigned a seat number. This is done automatically for all discussion units, when they are connected to the DIS-CCU. The DIS-CCU Browser interface is used to change seat numbering.

Seat numbers must be in the range from 1 to 65535.

DIS-CCU Reply to Commands

Generally, a command from an external application is replied to by the CU. But, reply to a command is produced only if actions are taken by the CCU due to the command.

Example: When a 'mic_on' command results in a microphone being turned on, the CCU replies with a 'mic_on' command. On the other hand, if a 'mic_on' command does not lead to turning on a microphone, the CCU does not produce any reply.

There can be several reasons for the CCU to reject turning on a microphone:

  • The microphone is already on
  • The microphone is no longer connected to the system
  • Speak list is already full ('max_speakers') and delegate interrupt is not 'on'

Retrieving System Status

The CCU supports streaming of status. When an External Control issues a 'mic_status' or 'audio_status' command, the CCU responds by sending the microphone system status. The same applies to 'audio status'. Therefore, it is possible for an External Control to synchronize with the CCU status.

Microphone Control

Commands from External Control to DIS-CCU

Turn on microphone

mic_on <seat no><CR>

Instruct the CCU to turn on the microphone at seat_no.

If the CCU turns on the microphone, it replies with the 'mic_on' command. If the microphone also appeared in the request list, it is taken out of the request list and the CCU issues the 'mic_request_off' command.

Turn off microphone

mic_off <seat no><CR>

Instruct the CCU to turn off the microphone at seat_no.

If the CCU turns off the microphone, it issues a 'mic_off' command.

Turn off all the delegate microphones

mic_all_delegates_off<CR>

Instruct the CCU to turn off all delegate microphones.

A Chairman is not turned off.

The CCU responds to the command by issuing the 'mic_off' command for each microphone that is turned off.

Put a microphone in the request list

mic_request_on <seat no><CR>

Retrieve the Microphone Status

mic_status<CR>

Ask the CCU to deliver status of the system (microphones in speak, and microphones in request list).

The CCU issues the microphone system status. The status is a list of commands from the CU:

seat_number (for all microphones in the system)

mic_mode

mic_interrupt

max_total_speakers

max_speakers

max_requests

mic_on (for all microphones on)

mic_request_on (for all microphones in request list)

mic_status_done

Help

help<CR>

help <command><CR>

Help is available for all commands supported by the CU. If a command is included after the help command, details on that command is issued by the CU.
